NEC qualifies subsea repeaters and cables for 24 fiber pairs

 NEC and its subsidiary OCC Corporation have completed full qualification of subsea repeaters and optical cable containing up to 24 fiber pairs (FPs) (48 fibers). The new qualification is a 50% improvement in fiber count over the 16 fiber pair systems generally available today. 

Only minor modifications were needed to NEC's existing repeater and cable designs. Keeping NEC's quadruple pump redundancy in the repeater (established more than 10 years ago) and maintaining OCC's outstanding cabling performance has resulted in cabled attenuations lower than 0.150dB/km. Low attenuation is critical to achieve large spectral efficiency as well as lower power consumption.

NEC said the qualification will allow for the construction of subsea telecom cables with superior traffic capacity while reducing the cost per bit of the wet plant. The development is fully in line with SDM (Space Division Multiplexing) system architectures. 

"As global demands for capacity and FP flexibility continue to soar, NEC is committed to helping our customers to build up their subsea networks with large spectral efficiency, lower power consumption and large-scale subsea connectivity," said Yoshihisa Inada, Deputy General Manager and Head of Subsea Technology Development at NEC's Submarine Network Division.  "We continue to evaluate multiple technical options to further increase capacity and reduce the cost/bit of the networks."

OCC's 24 fiber pair cable can be manufactured using a wide range of existing optical fibers, according to the needs of each new cable system. Each fiber can be visually identified using a field-proven combination of ring marking and conventional fiber coloring, first introduced in 2013. Furthermore, in OCC cable, the fiber's transmission performance is completely unaffected, either by the fiber marking or cabling processes.

"We have concluded that the use of our fibers in OCC's 24 pair cable results in a cabled attenuation matching the nominal value. We are confident that our ultra-low-loss fibers can contribute to achieve large capacity, high spectral efficiency and low power consumption in transoceanic networks," said Dr. Masashi Onishi, General Manager at Optical Fiber and Cable division of Sumitomo Electric Industries Ltd.

"To support growing bandwidth, next generation subsea systems will offer Petabit-scale transmission. To achieve the required performance, cabling processes must capture the advantaged optical attenuation and large effective area of our ultra-low-loss fibers. OCC's cabling process for 24 fiber pairs works with our high quality fiber to meet the challenge," said Dr. Bernhard Deutsch, VP & GM, Optical Fiber & Cable, Corning Incorporated.

NEC targets subsea cables to 24 fiber pairs and beyond

NEC and its subsidiary OCC Corporation completed full qualification of subsea repeaters and optical cable containing up to 20 fiber pairs (40 fibers). This represents a 25% improvement in fiber count over 16 fiber pair systems previously built by NEC. NEC said it achieved this milestone with only minor modifications to its proven repeater and cable designs. This was done by optimizing key repeater components, and by proving that its existing cable...

NEC delivers submarine cable seismic and tsunami observation system

NEC has delivered a submarine cable seismic and tsunami observation system to Taiwan's Central Weather Bureau (CWB) under the Ministry of Transportation and Communications. The new system is mainly intended for observation of earthquakes and tsunami in the area ranging from the offshore coast of Yilan in eastern Taiwan to Fangshan in Pingtung County. 

The submarine cable measures 620 kilometers and reaches a depth of 5,800 meters. All products, including optical submarine cables, submarine observation units, and optical submarine repeaters, which constitute the system, were manufactured and assembled at NEC factories in Japan.

According to the CWB, when an earthquake occurs in the eastern sea area of Taiwan this new system can provide an emergency warning more than 10 seconds before the actual tremor is felt on land. Moreover, a warning can be issued 20 to 30 minutes before a tsunami reaches the coastal area. As a result, this system will contribute to the enhancement of disaster prevention and mitigation capabilities. For example, public transportation systems, including MRTs (Mass Rapid Transit) and HSRs (High Speed Rail) can quickly decelerate in the event of an earthquake.

Atsushi Kuwahara, General Manager, Submarine Network Division, NEC Corporation, said, "It is a great honor that the NEC Group can use its many years of experience in optical submarine cable communication technology and submarine observation technology to help prevent disasters and ensure safety for the residents and government of Taiwan. Going forward, we will continue to provide technology and solutions that contribute to the well-being of our communities."

NEC triples number of connections in distributed-MIMO

NEC demonstrated multiple highly stable simultaneous terminal connections and transmission capacity through distributed-MIMO in the 28 GHz millimeter-wave frequency band. 

The company says its demonstration, which was conducted in a real world office environment, achieved approximately 3 times the number of simultaneous connections and transmission

capacity compared to cases without distributed-MIMO in the 28 GHzfrequency band. Moreover, transmission deterioration from obstacles was also reduced.

Earlier this year, Japan began to commercially deploy 5G in the sub 6 frequency band and millimeter-wave frequency band, with the expectation of enhancing network performance to support 10 times more capacity than 4G, as well as higher throughput, lower latency, and multiple connections.

NEC has been a pioneer in digital beamforming technology and has commercialized Massive-MIMO in the sub 6 frequency band. Moreover, NEC has developed digital coordination technology among antenna elements distributed in the millimeter-wave frequency band and conducted verification activities to solve the problems of indoor mobile communications, such as shadowing and diffraction of propagation paths.

NEC to build subsea cable in Palau

The National Submarine Cable Utility Belau Submarine Cable Corporation (BSCC) of the Palau Republic (Palau) has awarded a contract to NEC for the construction of the Palau Cable 2 (PC2) optical submarine cable.

The PC2 cable will have a total length of approximately 110km and connect Palau with another high-capacity cable linking southeast Asia to mainland U.S.  The new cable serves as an addition to the first optical submarine cable laid by NEC in Palau in 2017.

This project is being implemented under a buyer's credit loan agreement by the Japan Bank for International Cooperation (JBIC) and Sumitomo Mitsui Banking Corporation (SMBC)

with BSCC. The loan portion from SMBC is insured by Nippon Export and Investment Insurance (NEXI). Additional financing is being provided by the United States Government and the Australian Infrastructure Financing Facility for the Pacific (AIFFP).


NEC begins construction of 3 subsea cables in Micronesia

NEC, in partnership with Belau Submarine Cable (BSCC) and the government of the Federated States of Micronesia (FSM), announced it has commenced construction of three submarine cable links that will connect the islands of Palau, Yap and Chuuk in the western Pacific Ocean to the global network.

BSCC, supported by a loan from the Asian Development Bank (ADB), has signed a supply contract with NEC to build the spur to Palau, while FSM, backed by a grant from the World Bank (WB), has signed a supply contract with NEC to construct the spur to Yap, and recently signed an additional agreement for the extension from Pohnpei to Chuuk.

The spurs to Palau and Yap will both interconnect with the SEA-US cable system, also under construction by NEC, which connects the Philippines and Indonesia to the west coast of the U.S. via Guam and Hawaii. In addition, the extension from Pohnpei, the capital of FSM, to Chuuk branches out of another existing cable linking FSM, the Marshall Islands and Guam. All three routes feature transmission speeds of 100 Gbit/s per channel.

BSCC is a state-owned entity of the Republic of Palau with responsibility for the submarine cable project. BSCC has signed an IRU agreement with GTI (a subsidiary of Globe Telecom) for the provision of 5 x 100 Gbit/s wavelengths and a branching unit (BU) on the SEA-US West subsystem linking Indonesia, the Philippines and Guam. It has also contracted NEC to supply a spur cable linking the BU on the SEA-US West subsystem to Palau.

On completion of the project, BSCC will provide open bandwidth access to the international cable system for domestic telcos.

In addition, DTCI has signed an IRU agreement with Telkom Indonesia (Telin) for 5 x 100 Gbit/s wavelengths and a BU on the main trunk of the SEA-US West subsystem, plus a supply contract with NEC to deliver a spur cable linking the BU on the SEA-US West subsystem to Yap, along with a contract extension that includes a cable linking Weno Island Chuuk to the existing spur on to the HANTRU-1 cable system in Pohnpei to Guam.

Ownership and implementation responsibilities for the cable systems will pass from DTCI to the newly established FSM Telecommunications Cable (FSMTCC) which, as owner of the Yap and Chuuk cable systems, will provide open bandwidth access to the international cable systems for domestic telcos.

Rakuten tests O-RAN 5G Massive MIMO with Altiostar and NEC

Altiostar confirmed that its O-RAN Alliance-compliant multi-vendor massive-multi-input, multi-output (mMIMO) 5G solution is in now in testing with with NEC Corporation and Rakuten Mobile.

Specifically, Altiostar is integrating the O-RAN distributed unit (O-DU) functionality of its virtual radio access network (vRAN) software with NEC's O-RAN Radio Unit (O-RU) using fully compliant control, user, synchronization and management (C/U/S/M) plane protocols based on O-RAN Alliance guidelines. The 5G layer is built using container network functions (CNF) that leverage Rakuten Mobile's cloud infrastructure platform that is part of its 4G network build out.

As part of management-plane integration, Altiostar is following a hierarchical model that allows the O-DU software to manage the NEC O-RU, including providing software upgrades, RU configuration, fault management and performance monitoring. This interoperability is being performed for 5G new radio (NR) sub-6 GHz massive MIMO O-RU and meets all the 3GPP downlink/uplink (DL/UL) requirements.

"Open RAN as a concept is one that the whole industry is now actively pursuing as a means to introduce supply chain diversity into mobile networks globally," said Ashraf Dahod, CEO of Altiostar Networks. "Altiostar is leading the industry with this network transformation by ensuring interoperability, integration and most importantly extensive testing to ensure that we have a commercial, carrier-grade solution for both 4G and 5G while keeping the principles of Open RAN in place."

"Rakuten Mobile is a big supporter of O-RAN principles and has seen the benefit of supply chain diversity in our own network," said Tareq Amin, Representative Director, Executive Vice President and Chief Technology Officer of Rakuten Mobile. "By combining the spectral efficiency of massive MIMO along with an advanced cloud-based RAN, we are leveraging and introducing advanced innovative technology from both NEC and Altiostar, who are specialists in these respective fields."

Altiostar's container-based 5G solution splits the baseband into the CU and DUs using micro-services to disaggregate these RAN workloads at a deep level. The DU provided by Altiostar is interoperable with, and uses, O-RAN compliant interfaces to work with third-party O-RUs. These workloads can be deployed flexibly to support different quality of service (QoS) and other requirements of the 5G network slice.

The Altiostar containerized architecture also intrinsically introduces Control and User Plane Separation (CUPS). Thus, containers that support IoT can be sized differently when compared to other workloads, such as enhanced Mobile Broadband (eMBB) applications. Alternatively for ultra-reliable low latency communications (UrLLC) applications like V2x or augmented reality, the operator can dynamically deploy the user plane containers at far-edge locations.

NEC has designed its 5G Radio Unit (RU) as an active antenna array system (AAS) that consists of an RF front end and a massive-element antenna in order to minimize the system footprint and provide high-efficiency.

NEC's AAS utilizes a fully digitized antenna beam control technology that improves the precision of beam forming. While transmitting beams to the target mobile handsets, it is capable of forming beams that counteract interfering signals using multi-path. It can also form beams that improve communication quality by efficiently combining the multi-path of its own signals with the direct waves.

The features of NEC's AAS enable concurrent communication with several handsets, even though they are close to each other, while maintaining high communication quality. In the trials, NEC proved that use of the AAS can result in improved capacity and quality of communication between a base station and handsets, while confirming that spectral efficiency was reliably maintained at a level roughly eight times higher than that achieved by LTE in indoor environments.

NEC hits 10Gbps with outdoor radio in the 150GHz-band

NEC has demonstrated bidirectional 10Gbps outdoor transmission over a span of 150m using all-outdoor packet microwave radios operating in the D-band (130-174.8GHz). The radios use customized RF modules powered by a new RF IC chipset.

In the demonstration, the frequency points for the transmitter and the receiver were 142GHz and 157Hz respectively, the modulation scheme was 128QAM, and modulation speed was 1.6Gbaud.

NEC plans to support this technology in its iPASOLINK series of super compact microwave radio products. Targeted applications include both mobile fronthaul and backhaul networks, which are required to be ultra-high capacity in order to support 5G commercialization.

Additional field tests were conducted throughout a 4 month period over an approximate 1km link distance as part of preparation for practical applications. Going forward, NEC is seeking to confirm parameters necessary for link design based on the recommendations of the ITU-R (*2), such as how to expand to D-band when considering the relationship between rainfall and communication availability.

NEC and Mavenir to deliver 5G Open vRAN

NEC and Mavenir will jointly develop a 5G Open virtualized RAN (vRAN) solution for the Japanese enterprise market. This will open up Local/Private 5G Network opportunities for enterprises, regional authorities and other organizations.

Under this collaboration, NEC and Mavenir will jointly work on 5G Open vRAN and Local 5G business developments. The collaboration will bring together NEC’s expertise in IT, network and system integration and Mavenir’s field-proven cloud-native network technology.

Mavenir said its Open vRAN solution is differentiated by enabling multisource Remote Radio Units (RRUs) to interwork with the virtualized, containerized, Cloud Base Band software over ethernet Fronthaul (FH), using the O-RAN open interface, overcoming the traditional constraints of the proprietary walled garden specifications used by the other traditional equipment vendors.

NEC actively promotes an open, virtualized infrastructure model in support of the 5G era, utilizing IT, orchestration and network expertise. Moreover, the NEC ecosystem contributes to vRAN via interoperability testing between multiple vendors’ equipment that is compliant with O-RAN fronthaul specifications.

“We are excited to collaborate with NEC, as we move together toward open, virtualized networks,” said Pardeep Kohli, Mavenir’s President and CEO. “Mavenir’s vRAN and NEC’s radio naturally come together to quickly and easily bring new and innovative solutions to the Japanese Enterprise Market.”

“The combination of advanced assets and expertise from Mavenir and NEC will enable us to offer end-to-end one-stop 5G Open vRAN and Local/Private 5G solutions, including an advanced 5G network solution for the ecosystem, and vertical solutions that meet the needs of a great variety of Enterprise customers,” said Nozomu Watanabe, senior vice president at NEC.

NEC targets subsea cables to 24 fiber pairs and beyond

NEC and its subsidiary OCC Corporation completed full qualification of subsea repeaters and optical cable containing up to 20 fiber pairs (40 fibers). This represents a 25% improvement in fiber count over 16 fiber pair systems previously built by NEC.

NEC said it achieved this milestone with only minor modifications to its proven repeater and cable designs. This was done by optimizing key repeater components, and by proving that its existing cable design could easily accommodate more fibers. The 20 fiber pair repeaters continue to use quadruple pump sharing technology, first introduced by NEC in 2010, for high optical and electrical efficiency.

OCC’s 20 fiber pair cable can be manufactured using a wide range of existing optical fibers, according to the needs of each new cable system. Furthermore, OCC has demonstrated to its customers that they can visually identify individual fibers using a combination of ring marking and conventional fiber coloring. This allows the potential number of fibers in a cable to be greatly expanded. Significantly, in OCC cable, the fiber’s transmission performance is completely unaffected, either by the fiber coloring or cabling processes.

“As global capacity demand continues to soar, NEC is committed to helping our customers scale up their networks in a cost-effective way,” said Takaaki Ogata, Executive Technical Manager of NEC’s Submarine Network Division. “Further significant increases in the fiber pair count of NEC’s wet plant are coming soon,” he added.

Mass production of the newly-qualified subsea repeaters and optical cable has already started.
